To determine which graph most accurately represents the energy of a person on a swing at position 1, we need to consider the forms of energy involved: potential energy (PE) and kinetic energy (KE).
1. **Position 1**: If position 1 is at the highest point of the swing's path, the person will have maximum potential energy and minimal kinetic energy (as they momentarily stop before swinging back down).
2. **Energy in a Swing**:
- Potential Energy (PE) is highest at the highest point of the swing's arc.
- Kinetic Energy (KE) is highest at the lowest point of the swing's arc.
Given these principles:
- If position 1 corresponds to the highest point of the swing, then you should expect a graph where potential energy is at its maximum, and kinetic energy is close to zero.
Now, evaluate each graph (A, B, and C) to see which one aligns with this concept:
- Look for a graph that depicts high potential energy and low (or zero) kinetic energy at that position.
If you can use this rationale to analyze the graphs provided, you'll be able to choose the correct one. If none of the graphs aligns with these expectations for position 1, then the answer would be D. However, without the specific graphs in front of us, I can't specify which graph is correct.
